Title: Improvements relating to audible warning devices
Inventor: LALLY PATRICK JOSEPH
IPC: G08B3/10
Filed: 1985-03-13
Abstract: A method of improving the safety of road-works 21 comprises placing an audible warning device 20 at the road-works to alert blind or visually impaired pedestrians 23 to the road-works. The audible warning device includes a sound generator emitting a pulsed warning signal which may be automatically adjusted, to compensate for ambient noise levels, by means of an ambient sound control unit. Alternatively a generating unit emitting an electronic signal may be placed at the road-works, the electronic signal activating a receiver/sonic transmitter carried by the pedestrian. Or the generating unit may be carried by the pedestrian and the receiver/sonic transmitter may be placed at the road-works. The audible warning device may be disguised as a brick or a piece of timber, or may be incorporated in a hazard warning light. In a further form, the audible warning device is included in a vehicle door and is activated upon opening the door. <IMAGE>
Patent GB-2157460-A (GB)
Title: Adjustment mechanism for the displacement volume of a displacement machine
Inventor: NAGEL GUNTHER
IPC: F04B49/12
Filed: 1985-04-10
Abstract: The adjustment mechanism in accordance with the invention is preferably intended for a radial piston pump (10). Its displacement volume, and consequently its feed current, depends on the position of a piston guide ring, which is movable by means of an adjustable piston (11). Pressure acting on the adjustable piston can be varied by means of a control valve (20). Between the valve body of the control valve and the adjustable piston is fixed a pressure spring (29). The force of this spring is a measure for the actual value of the feed current. A desired force which is formed by a desired value (X1 or X2) works against the force of the spring. The desired value is produced by a producer (23, 24) which has a desired value limiter (40). This can be activated when the feed pressure exceeds an adjustable pressure boundary value. The adjustment of the pressure boundary value occurs by a computer (43) as a function of the quotient from the maximum permissible feed performance (P) and the instantaneous feed current (Q). The latter is measured by a displacement pickup (49) which is connected to the adjustment piston.   <IMAGE>

Title: Heating and mixing process
Inventor: HARE ALAN LAWRENCE
IPC: B01J23/745
Filed: 1986-07-17
Abstract: A process for heating and mixing an iron oxide catalyst involves feeding powdered iron oxide into a receptacle into which an electric arc is directed from a first electrode 30 to a second 32 and in the receptacle the iron oxide is melted and mixed with one or more catalyst promoters. The arc has been found to stir the molten mixture and produce good dispersion of the promoters throughout the molten iron oxide and in its most preferred form the iron oxide is magnetite and when mixed with the promoters can be used as catalyst in the synthesis of ammonia. Single or multiple arc arrangements may be employed. <IMAGE>

Title: Acoustic load device
Inventor: NICHOLLS BERNARD HARRY
IPC: H04R29/00
Filed: 1988-05-12
Abstract: An acoustic transducer intended for underwater use can be tested in air by a load device which simulates the underwater conditions. The load device 1 comprises a body 3 of a lossy polymer composition, means for holding said body in contact with an output surface 6 of the transducer, and a clamp 2,8 to press the body against the output surface 6.

Title: Seal for insert valve for pipelines or the like
Inventor: MORGAN IAN HENDRY
IPC: F16K27/04
Filed: 1989-04-07
Abstract: A seal 21 for an insert valve for a subsea pipeline is fitted to a groove 20 in each sealing face 19 of the removable valve body 16. The seal 21 is annular and specially profiled having a cone shaped surface 32 which engages a cone- shaped surface 36 in the groove 20. Surfaces 32, 36 have an angular mismatch so that on initial contact therebetween only a radially inward portion of surface 32 engages surface 36 leading to diametrical size reduction of the seal 21 and localised plastic deformation along surface 32 to provide full sealing engagement with surface 36. High pressure fluids flowing through the valve tend to enlarge the diametrical size of the seal 21 and hoop stresses in the seal enable expansive recoil thereof in the groove 20 without loss of sealing effect. <IMAGE>

Title: Gas pressure control apparatus
Inventor: LTD INTERNATIONAL GAS APPARATU
IPC: G05D16/16
Filed: 1989-04-18
Abstract: Gas pressure control apparatus comprises two streams 12A and 12B connected in parallel between a high pressure inlet 10 and a low pressure outlet 11. Stream 12A includes a slam-shut valve 15A followed by pressure regulating means 16A; stream 120 is similar. Control means sense the failure of the regulating means in a stream and close the slam-shut valve of that stream. If the regulating means of a channel fails, the control means closes both slam-shut valves on a rise of outlet pressure (by path 25A to control valve means 26A, 27A, 21A, and 20A and likewise for stream 120), determines the resulting pressure difference between the two streams following the slam-shut valves (by valve 30, controlled via 34A and 340), and re-opens one of the slam-shut valves (via path 31 to the appropriate control valve means). An electronic control system can alternatively be used. <IMAGE>

Patent GB-2233495-A (GB)
Title: Thermal-radiation detectors, detection systems and their manufacture
Inventor: TURNBULL ANDREW ALFRED
IPC: H01L37/02
Filed: 1990-04-06
Abstract: In a thermal-radiation detection system, ferroelectric or pyroelectric detector elements (20) are mounted on flexible platform areas of an insulating substrate (10) which may be of an elastic material such as a silicone rubber in, for example. an apertured or recessed mount (18, 19). The grooves (15) forming the platform areas have a sufficient depth d and width w that the distance (2d + w) is at least as large as the thermal diffusion distance at the modulation frequency (f) so as to reduce thermal cross-talk between the detector elements (20). The elasticity and vibration absorption properties of an elastic substrate (10) and the flexibility and path length increased by the presence of the grooves (15) can provide a low microphony mounting arrangement with acoustic decoupling between detector elements (20). Preferably the groove depth d is at least as large as the thermal diffusion distance so as to reduce thermal losses from each detector element (20) and increase the acoustic path length and flexibility of the mounting. The substrate (10) may be moulded with the grooves in its face (11), or the grooves may be cut with a saw. The incident radiation is periodically modulated. <IMAGE>

Title: Blasting with particulate material
Inventor: JACKSON ROBERT SIDNEY
IPC: B05B7/14
Filed: 1990-08-04
Abstract: Apparatus for performing a process of cleaning surfaces of buildings comprises a chamber (11) partitioned by a pyramidal barrier means (33) into lower and upper zones (35a, 35b). Low velocity gas is impelled from a perforated body (15) to fluidize a bed of particulate material (13) particles of a certain energy escaping to a handpiece (21) by way of escape means (19). The bed is maintained in a steady state by the descent under gravity of particulate material (37) upheld by the barrier means (33), the material (37) and the material (13) forming a continuum at the peripheral communicating passage (41) of the barrier means. Gas at high velocity along passage (25) and six passages (95) in a swirl imparting member (79) entrains particles carried by the low velocity gas along passage (23) at the junction (27) of the passage (23) with the passages (95). As the particulate material attains the junction it is immediately accelerated by the high velocity gas to its discharge velocity from the handpiece.

Title: A re-usable,air pressurized tranquilliser dart
Inventor: CROOKS STEPHEN CHARLES
IPC: F42B12/54
Filed: 1990-10-19
Abstract: A tranquilliser dart has a head (1) of certain outside dimension, releasably fixed to a barrel (2) of substantially smaller outside dimension. This barrel contains a rubber piston (5). The aforementioned head possesses an integral hypodermic needle (7), this needle has a hole in the side, near the said point. The hole in the needle is sealed by a rubber sleeve (6). Permanently fixed to the barrel (2) at the opposite end to the head (1) is a flight ring (3) and a one piece ventable valve (4). The said valve allows compressed air to be pumped into the rear of the dart by means of a venting needle (8) and ordinary hypodermic syringe (9). The said valve (4) maintains the air pressure during use of the dart. The said valve also allows the air pressure to be drawn out of the rear of the loaded dart by means of the venting needle, thus making the dart safe.
